Semi-removable Mass Stove + (Semi-removable inertia mass stove. A mass … Semi-removable inertia mass stove. A mass storage stove or ‘heat storage stove’ is a primary heating device. Its mass, which is made up of heavy material (stone, brick and concrete), stores energy from a fire that burns once during the day (lasting between 1 and 3 hours). Once the fire has gone out, it then continues to give out heat over a prolonged period (for up to 24 hours). Its mass provides thermal inertia which helps to keep an even temperature inside a building (which is why these stoves are often also called “inertia stoves”). The whole of the quantity of wood needed to heat the dwelling is burnt in one go, making it burn hotter which allows complete and more environmentally-friendly combustion. It is a storage device which is designed to absorb the bulk of the energy that is generated from combustion and exhaust gases, which cool down considerably once out of the stove. Accumulated heat is mainly diffused by radiation and, in a few cases, by convection. This particular type of heating, i.e. that uses radiation, is best located in the centre of the dwelling and therefore, most mass stoves these days are positioned in the main room which opens out onto the lounge, dining room and kitchen. As yield tends tend to be in the majority of cases higher than 80%, these stoves are considered to be one of the most efficient wood-fuelled heating devices.

Orangepi-raspberry pi nextcloud server (photovoltaics powered) + (Tutorial to setup a nextcloud server (equi … Tutorial to setup a nextcloud server (equivalent to google drive but free and adapted to collective organisations) on a single board computer (photovoltaics powered)

This tutorial is not really "lowtech" at first look because we talk about computers and photovoltaics

However it is as didactic as possible and follows a lowtech philosophy to share knowledge, avoid unreachable tech by information rentention, complexification by design, or proprietary dependance by design.

We also give sizign tools for photovoltaics with a few explanation. It's up to to you to size your computer working hours on a sun schedule, ie respecting human temporalities.

Nextcloud (framasoft offers a service here: https://www.frama.space/abc/fr ) is a cool service to organise collectively and allows to share files, have a directory, a chat, work cooperatively on libreoffice files, and even do visios. We can also imagine mobile infokisosks on this principle.

The tutorial puts into question the vpn market, the phtovoltaics with brand new and expensive batteries (in reality photovoltaics has become too competitive compared to petrleum and even more compared to nuclear power!), and the gafam market and their surveillance design is damaging trust and social links. The commands are those for a debian system

Finally, the tutorial is made iwth 4G modem (and a wired connection to orange pi which has no wifi card by default), and is updated on this 10th of april for a raspberry pi connected to a "shared wifi" of your telephone (see stage 6 for a wifi in wpa3 and stage 16 for a wifi in wpa2)pi connected to a "shared wifi" of your telephone (see stage 6 for a wifi in wpa3 and stage 16 for a wifi in wpa2))

Ce tutoriel n'est pas tout à fait "lowtech" en première approche dans la mesure où il s'agit d'informatique et de photovoltaique.

Cependant, il se veut le plus didactique possible et rejoint la philosophie lowtech de partager les savoirs faires, éviter la tech inaccessible par la rétention d'information, la complexification by design ou la dépendance propriétaire by design.

On donne aussi un outil de dimensionnement photovoltaïque avec quelques explication. A vous de dimensionner pour une informatique lowtech, qui ne fonctionne que sur une plage horaire calé sur les rythmes du soleil, cad qui respecte les temporalités humaines.

Nextcloud (service accessible sur framasoft ici : https://www.frama.space/abc/fr/) est un service assez cool pour s'organiser à plusieurs et permet de partager des fichiers, avoir un annuaire, un chat, de travailler en cooperation sur des fichiers libreoffice voire même de faire des visios. On peut aussi imaginer des infokiosques mobiles sur ce principe.

Le tuto remet en question le marché des vpns, le photovoltaique avec stockage neuf et cher (en réalité le photovoltaique est devenu trop competitif face au pétrole et encore plus face au nucléaire!), et le marché des gafam et leur design de surveillance nocif pour la confiance et le lien social.

Les commandes sont celles pour un systeme debian

Enfin, le tuto est fait avec un modem 4G (et connexion filaire à un orange pi qui n'a pas de carte wifi par défaut), et mis a jour ce 10 avril pour raspberry pi connecté au "partage wifi" de votre téléphone. (voir etap 6 pour wifi en wpa3 et etap 16 pour wifi en wpa2) pour raspberry pi connecté au "partage wifi" de votre téléphone. (voir etap 6 pour wifi en wpa3 et etap 16 pour wifi en wpa2))
